Sisir Radar’s Polarimetric L-band SAR data, collected from 1st to 9th April 2025 across 22 datasets, has been overlaid on Google Earth, highlighting the system’s exceptional geometric precision and radiometric consistency in real-world terrain mapping.

Sisir Radar is conducting repeated drone flights over similar terrains to refine operating conditions for its upcoming space-borne L and P band SAR constellation. Preliminary findings reveal strong foliage penetration at low incidence angles, balanced structural returns up to 30°, and increasing foliage dominance beyond, offering valuable insights into polarimetric behaviour.

Sisir Radar presents a compelling animation aligning 1 m resolution drone-borne L band SAR imagery with recent Airbus-captured Google Earth visuals, offering followers a rare chance to compare polarimetric SAR signatures with optical imaging and validate geometric fidelity.

At Startup Mahakumbh, Sisir Radar showcased a global breakthrough—the highest-resolution L+P dual-band SAR system. Honoured by the presence of DRDO leadership and top defence scientists. The breakthrough drew wide interest from industry leaders, affirming our vision for cutting-edge radar solutions in defence and space tech.

Captured over two weeks, Sisir Radar’s P band SAR time series showcases 2.5 m unmatched resolution with hybrid polarimetry. Despite long aperture times and challenging drone flight conditions, the system delivers exceptional radiometric and geometric fidelity, setting a new benchmark in P band imaging.

Sisir Radar’s highest resolution Polarimetric P band SAR reveals strong surface and subsurface returns with minimal foliage interference, making it a powerful tool for detecting buried features and analysing ground volumes. L band continues to be effective for capturing both vegetation and sub-foliage structural signatures.
